Definition
CAPITAL carries two largely independent legal meanings that share only their derivation from a common Latin root. Context — criminal, commercial, or corporate — determines which applies.
1. Capital (adjective) — criminal law. Relating to punishment by death. A capital offense is one for which death is a legally authorized penalty. Capital punishment is the sentence of death itself. Capital proceedings are those in which the defendant's life is at stake. The adjective is not synonymous with "serious" or "felony" — it has a precise technical meaning tied to the ultimate penalty.
2. Capital (noun) — commercial and corporate law. The fund of money or property committed to a business enterprise and available to support its operations. In partnership law, capital is the sum each partner contributes to the common stock. In corporate law, capital refers to the aggregate of shareholders' contributions — often distinguished from income or profit, which are generated by deploying that fund. Related terms include authorized capital (the maximum a corporation may issue), paid-in capital (amounts actually received from shareholders), and stated capital (the portion of paid-in amounts assigned to the par value of shares). Capital is distinct from revenue: capital is the base; revenue is what the base produces.
Common Language
Modern common usage (Wiktionary): "Of prime importance"; "punishable by death"; "uppercase" (as in a capital letter); "excellent" (informal British).
Historical common usage (Webster's 1913): "First in importance; chief; principal"; "having reference to, or involving, the forfeiture of the head or life; affecting life; punishable with death."
The common language preserves both the "chief/principal" sense and the "death penalty" sense, but the commercial meaning — capital as invested fund — is largely absent from ordinary usage. A researcher reading a 19th-century document describing a company's "capital" as its "chief fund" is encountering a fusion of both senses that modern readers may not immediately recognize as a technical term of art.
Common Confusion
Three distinct uses of "capital" create research traps:
First, capital (adjective, criminal) versus capital (noun, commercial) share a word but occupy entirely different legal domains. A document index entry for "capital" may surface criminal procedure records alongside corporate finance instruments.
Second, capital as invested fund is frequently confused with capitalization (the total market value of outstanding shares) and with surplus (amounts received above par value). These are related but not interchangeable, and the distinction matters in corporate law, tax treatment, and insolvency analysis.
Third, the informal use of "capital" to mean "chief" or "principal" — as in "capital burgess" or "capital city" — appears in older English legal materials without either the death-penalty or the commercial-fund meaning. Burrill notes usages such as "capital burgess" and "capital citizens," which simply mean the leading or chief member of a class. Treating these occurrences as references to either criminal or commercial capital produces misreadings.

Why It Matters in Research
The dual meaning of "capital" creates genuine indexing and search problems in the Law Mind corpus. A full-text search will return criminal law materials (capital punishment, capital felony) alongside corporate and commercial materials (capital stock, stated capital) with no automatic disambiguation. Researchers must filter by subject area or document type before treating search results as thematically related.
In historical sources, the commercial meaning of "capital" was less standardized than it is today. Bouvier uses it to mean the actual estate — money or property — owned by an individual or corporation, treating it as broadly synonymous with net assets. Modern corporate law draws sharper distinctions among authorized capital, issued capital, paid-in capital, and stated capital; these distinctions often did not exist in the forms used today when 19th-century treatises were written. A researcher tracing the development of corporate capital requirements should not assume that "capital" in an 1850 source means what "stated capital" means under a modern business corporation act.
For criminal law research, the key evolution is jurisdictional contraction. "Capital offense" once applied to a longer list of crimes in both English and American law; the category has narrowed sharply over time, particularly after the mid-20th century constitutional developments in the United States. A capital offense in an 18th-century source is not the same population of crimes as a capital offense under contemporary law.
In tax research, capital as a category — capital assets, capital gains, capital losses — is defined by statute and carries specific meaning under the Internal Revenue Code. These statutory definitions do not track the commercial or corporate law definitions of capital precisely. A gain on the sale of a capital asset is not simply any gain derived from a business's capital base.
Historical Dictionary Support
Burrill and Anderson both present the adjective and noun senses as separate entries, which is the cleanest approach. Burrill traces the adjective to the Latin capitalis, from caput (head or life), and links it explicitly to offenses punishable by death — "quod ultimum inducit supplicium" (that which induces the ultimate punishment). This framing, from Bracton, reflects the earliest English legal usage and remains accurate.
Bouvier focuses almost entirely on the commercial meaning, defining capital as the sum adventured in an undertaking or contributed to a partnership's common stock, and citing McCulloch for the proposition that capital signifies actual estate — money or property — owned by an individual or corporation. Bouvier's treatment anticipates the corporate law sense without fully elaborating the distinctions that later statutory frameworks would impose.
Anderson's entry is the most concise and captures both meanings cleanly: capital as adjective (punishable by death) and capital as noun (money or property invested in a business). His parenthetical note that the term probably derives from "decapitation" as a mode of execution reflects a once-common folk etymology that modern scholarship does not treat as definitive but that was widely repeated in 19th-century legal writing.
None of the historical dictionaries address capital in the tax sense — capital gains and capital assets as statutory categories — because that framework postdates them. Researchers using these sources for tax research will find only the general commercial foundation, not the specialized meaning that modern tax law has built upon it.
Jurisdictional Note
In criminal law, which offenses qualify as capital varies by jurisdiction and has changed significantly over time; in the United States, constitutional constraints now limit capital punishment to a narrow category of the most serious crimes. In corporate law, the definition and treatment of stated capital, par value, and legal capital varies meaningfully among state business corporation statutes; many states have moved away from par value and stated capital requirements, while others retain them.
